The Galaxy is thriving with life. Bioware, the God of our massive Universe, is as kind and caring as he is omnipotent. From the smallest Space Hamster to the largest Tresher Maw, Bioware shows great care for his creations, and is always willing to give them the treatment they deserve.

That is, nobody except ONE person. See, in a universe filled with diversity and acceptance of differing cultures, there is one man who does not fit in. One man who does not agree with the social order. One man who dares speak up against the oppression of his beliefs! That man is...

Really though, it could go either way. They're probably an amalgamation of loads of things so it's not too obvious.
